About SupaSidebar

Universal Save & Copy Shortcuts

Effortlessly capture web content without interrupting your flow. With globally recognized keyboard shortcuts (Command + Control + S to save, Command + Control + C to copy the current URL), you can instantly send any link from any major browser directly into your SupaSidebar. This eliminates the tedious process of copy-pasting into separate note-taking apps or managing a chaotic bookmark bar, keeping your research and resources neatly organized in one dedicated, accessible space.

Recents & Favorites for Instant Recall

Never lose track of your work again. The "Recents" section automatically tracks every website you've visited in the last 48 hours, acting as a short-term memory for your browsing. For your essential tools, the "Favorites" (pinned items) feature keeps your most-used links, files, and apps permanently anchored at the top of the sidebar. This combination ensures that whether you're returning to yesterday's research or launching a daily dashboard, everything is just one click away.

Fast, Unified Search (CMD + CTRL + K)

Break down the barriers between apps and files. By pressing Command + Control + K, you activate a powerful, instantaneous search across your entire SupaSidebar library. This command bar lets you find and launch any saved website, local file, folder, or application without ever needing to switch contexts or dig through Finder windows. It's the fastest way to navigate your digital workspace, turning intention into action in seconds.

Native macOS Design & Privacy

SupaSidebar is built to feel like a natural extension of your Mac. It features a lightweight, unobtrusive interface that perfectly aligns with macOS aesthetics, appearing only when you need it. Critically, it operates with a strong commitment to privacy: all your data—every link, file reference, and organizational structure—stays locally on your machine. Nothing is sent to external servers, giving you complete control and peace of mind.
